Disclosed is a fireplace including a hearth (11). Upper air inlet openings (12) are arranged at the top part of the hearth (11) and lower air inlet openings (13) are arranged at the bottom part thereof. An upper guide plate (4), forming a first air inlet channel (112) together with a door (6) of the fireplace, is arranged at the front end of the top part of hearth (11). The first air inlet channel (112) is communicated with the upper air inlet openings (12), an outlet end of which is towards the bottom end of the hearth (11). A lower guide plate (5) is arranged on the bottom end of the hearth (11). The lower guide plate (5) is a concave plate with a concave surface faced toward a back wall (8) of the hearth (11). A second air inlet channel (111) arranged on the back wall (8) of the hearth (11) is communicated with the lower air inlet openings (13). Air inlet holes (81) which are communicated with the second air inlet channel (111) are arranged on the back wall (8) of the hearth (11). The airflow entering the fireplace via the first air inlet channel (112) and the second air inlet channel (111) forms an annular airflow in the hearth (11). The intake airflow entering into the hearth (11) provides large disturbance action, thereby avoiding dead angle of air supply and achieving complete combustion. |
